Abstract :
The design and realization of a long pulse optoelectronic isolator based on chopper and DSP (digital signal processing) technology are studied in this paper. According to the requirement of the optoelectronic isolator, a high-speed photocoupler 6N136 was used. By using the chopper and digital signal processor, a long pulse optoelectronic isolator without drift and a special circuit are designed and developed
